Oxygen Adjustable Venturi Mask with 6PCS Colored Venturi Connectors
A Venturi mask is a medical device used to deliver a known oxygen concentration to patients on controlled oxygen therapy. The mask utilizes the Venturi principle, which involves the use of a specific air entrainment device to mix a precise amount of supplemental oxygen with room air.
The oxygen adjustable Venturi mask typically comes with a set of colored Venturi connectors. These connectors are designed to deliver different concentrations of oxygen by controlling the air entrainment.
The different colors of the Venturi connectors correspond to specific oxygen concentrations, providing healthcare professionals with a quick visual reference. Each color represents a particular oxygen percentage, allowing for easy identification and adjustment according to the patient's respiratory needs.
The venturi mask, also known as an air-entrainment mask, is a medical device to deliver a known oxygen concentration to patients on controlled oxygen therapy.
The mask was invented by Moran Campbell at McMaster University Medical School as a replacement for intermittent oxygen treatment.
The colored Venturi connectors commonly represent different oxygen concentrations, such as:
- White: 24%
- Blue: 28%
- Yellow: 35%
- Red: 40%
- Green: 50%
- Orange: 60%

What is the difference between Venturi mask and oxygen mask?
1. Oxygen Mask:
- An oxygen mask is a broad term that encompasses various types of masks used to deliver supplemental oxygen to a patient.
- The basic oxygen mask is a non-rebreather mask, which covers the nose and mouth and allows a higher concentration of oxygen to be delivered without mixing with room air during inhalation.
- The flow of oxygen is typically set at a fixed rate on the oxygen source, and the concentration delivered to the patient depends on factors such as the mask design and the patient's breathing pattern.
- Oxygen masks are generally simple devices without built-in mechanisms to adjust the oxygen concentration.
2. Venturi Mask:
- A Venturi mask is a specific type of oxygen mask that utilizes the Venturi principle to deliver a more precise and controlled oxygen concentration.
- The Venturi mask includes an air entrainment device, which allows for the adjustment of the oxygen concentration by controlling the amount of air mixed with the oxygen.
- Venturi masks are equipped with color-coded Venturi adapters or connectors that correspond to specific oxygen concentrations. This allows healthcare providers to select the desired level of oxygen delivery.
- Venturi masks are particularly useful in situations where precise oxygen concentration control is essential, such as in COPD (chronic obstructive pulmonary disease) patients who require specific oxygen levels.
In summary, while an oxygen mask is a general term for devices delivering supplemental oxygen, a Venturi mask is a specific type of oxygen mask designed to provide a more controlled and adjustable oxygen concentration. The Venturi mask is often chosen in situations where precise oxygen titration is critical for effective therapy.
Nasal cannulas and simple face masks are typically used to deliver low levels of oxygen. Another type of mask, the Venturi mask, delivers oxygen at higher levels. Sometimes nasal cannulas are also used to deliver high levels of oxygen.
How many liters of oxygen can be given with Venturi mask?
The flow rate of oxygen delivered through a Venturi mask is typically specified in liters per minute (L/min). The actual oxygen concentration received by the patient depends on both the Venturi mask's design and the flow rate set on the oxygen source.
Each Venturi mask comes with a set of color-coded adapters or connectors, each corresponding to a specific oxygen concentration. The flow rates are usually marked on the mask or specified in the product documentation. Commonly used flow rates for Venturi masks range from 4 to 12 liters per minute.
Various entrainment devices can provide an FIo2 of 0.24 to 0.5, with an oxygen inflow of 4 to 15 l/min and a total flow delivered to the patient (including entrained air) of 35 to 45 l/min.
